Four Films That Tackle the Greatest Taboo

The House of Yes (1997): This film is the best of the lot. It also offers the best role for each of the actors who play the three siblings (Parker Posey, Freddie Prinze Jr., and Josh Hamilton are all brilliant) as well as for Tori Spelling (who plays a clueless working-class girl trapped in their web). Posey is Jacki- O, an unbalanced young woman who developed an intimate relationship with her twin brother, Marty, when two were just tweens (the younger version of Posey's character is  played by Rachael Leigh Cook of Premonition). When Marty returns home with his new fiancée, Leslie (Spelling in a hilarious role), Jackie-O is determined to set things right. Meanwhile, Mom, played brilliantly by Genevieve Bujold, tells Leslie that the two siblings belong to each other, that in fact Jackie's hand was holding Marty's penis when they came out the womb. There's less sex in the film than in some of the others on this list, but the stellar cast and the real erotic tension between Posey and Hamilton make this a must-see.
